Abstract

A plurality of panels (40) are cut out from a large-sized substrate (mother substrate) consisting of large-sized lower substrate (41A) and upper substrate (42A). In correspondence with each of these panels (40), a seal (47) and a connection electrode forming portion (C) are formed in frame-shape. Since the left side (47c) of the frame of one panel (40) is in close proximity to the right side (47b) of a left adjoining panel, seal members containing spacers tightly are arranged on these sides. On the other hand, since the upper side (47a) of the frame of one panel (40) is spaced apart from the lower side (47d) of an upper adjoining panel (40) while interposing an extension (c) for arranging the connection electrode, seal members containing spacers roughly are arranged on these sides.

Prepare large-scale infrabasal plate 1A and large-scale upper substrate 2A, use manufacture method such as printing that seal 7 is formed the shaped as frame shape therein on any one.Seal 7 with shaped as frame shape is corresponding to a panel, and as shown in figure 27, the frame of these seals 7 forms to be arranged in a plurality of forms on large-scale infrabasal plate 1A or large-scale upper substrate 2A.Part at frame is provided with cut channel, forms at the two ends of the seal 7 of this cut channel to the outstanding protuberance 7e in the outside of frame and with herein as inlet 7f.This inlet 7f becomes the inlet that is used to inject liquid crystal.

Seal 7 is made of the parts of interval adjustment component (separaant) 7n that has cooperated the width that is used to adjust the gap between the substrate on resin adhesive 7m, adjusts the amount (size) at the interval between large-scale infrabasal plate 1A and the large-scale upper substrate 2A with interval adjustment component (hereinafter referred to as separaant) 7n.Resin adhesive 7m private can be used heat curing-type bonding agent or ultraviolet hardening bonding agent etc.

The seal 7 that is configured to the shaped as frame shape is made of 4

sealing strip

7a, 7b, 7c, 7d.In these sealing strips, sealing strip 7a is relative with sealing strip 7d, and sealing strip 7b is relative with sealing strip 7c.Inlet 7f is located at sealing strip 7a side.

Make large-scale infrabasal plate 1A relative after on large-scale infrabasal plate 1A or large-scale upper substrate 2A, forming a plurality of seals 7, make the face of relative large substrate and the position consistency of parallel direction with large-scale upper substrate 2A with the shaped as frame shape.Then, applied in inboard, lateral and to have carried out heat treated or ultraviolet treatment with irradiation under the pressure, large-scale infrabasal plate 1A and large-scale infrabasal plate 2A are fitted from relative large-scale infrabasal plate 1A and large-scale upper substrate 2A.Fit to handle by this, as shown in figure 27, on large-scale infrabasal plate 1A and large-scale upper substrate 2A, arrange form a plurality of panel 10-1,10-2,10-3 ....

If large-scale infrabasal plate 1A and large-scale upper substrate 2A fit, then as shown in figure 28, in seal 7, form injection zone B, operation is injected the liquid crystal as the electric light converting member after this injection zone B.

In addition, large-scale infrabasal plate 1A is provided with the transparency electrode 3 of a plurality of shares and on this transparency electrode 3 alignment film 5 is set at the face of its liquid crystal side as shown in figure 28 in the mode corresponding to each panel.The transparency electrode 4 and the alignment film 6 of many shares also are set at the face of its liquid crystal side for large-scale upper substrate 2A equally.

Liquid crystal panel forms the C of portion by the connection electrode outside the frame of liquid crystal portion of having injected liquid crystal in the space of the seal that is the shaped as frame shape and seal and constitutes.Be electrically connected and transmit the connection electrode (or distribution electrode) of the signal that drives liquid crystal at the connection electrode formation C of the portion configuration and the electrode (mainly being pixel electrode and distribution electrode) in the zone that is disposed at liquid crystal portion.

In Figure 27 and Figure 28, represented corresponding to the seal that is the shaped as frame shape 7 of a panel and corresponding to and the seal that is the shaped as frame shape 7 of another panel of the vertical adjacency of this panel between disposed the figure of the connection electrode formation C of portion.This connection electrode formation C of portion is formed on the extension C ' that is arranged at large-scale infrabasal plate 1A.

As shown in figure 28, this connection electrode formation C of portion only is formed on the large-scale infrabasal plate 1A.In this connection electrode formation C of portion configuration connection electrode 9.This connection electrode 9 by drawing of being connected with transparency electrode 3 in the injection zone B of the electric light converting member of large-scale infrabasal plate 1A around electrode (or distribution electrode) with constitute to shift drawing on the large-scale infrabasal plate 1A that is connected the structure connection with the transparency carrier 4 of large-scale upper substrate 2A around electrode electrodes such as (or distribution electrodes).

Dot-and-dash line X1, X2, X3, Y shown in Figure 27 be used for from the large substrate (mother substrate) that constitutes by large-scale infrabasal plate 1A and large-scale upper substrate 2A cut apart a plurality of panel 10-1,10-2,10-3,10-4,10-11 ..., 10-21 ... (below, in these a plurality of panels, be referred to as " panel 10 " during any one panel in explanation) cut-off rule or cut off line.Cut off by cutting off line, obtain single panel along this.

At first, by cutting off large-scale infrabasal plate 1A and large-scale upper substrate 2A simultaneously, form a plurality of transversely arranged rectangular panels 10 along cutting off line X3.Then, use along the cut-out of cutting off line X1 and cut away regional K and trim the outstanding front end of protuberance 7e of the both sides of the inlet 7f that the opening portion that is located at seal 7 forms.Then, along cutting off the part D that does not want that line X2 cuts off upper substrate 2A shown in Figure 28.

After like this making rectangular substrate, inject liquid crystal as the electric light converting member from the inlet 7f of each panel.Afterwards, seal this inlet 7f.Then, cut off rectangular faceplate along cutting off line Y, thereby the panel that has obtained sealing liquid crystal is single liquid crystal panel (liquid-crystal apparatus).

Cut out a plurality of liquid crystal panels and form single liquid crystal panel from large substrate with aforesaid manufacture method.Yet if make panel with this manufacture method, the amount that constitutes the upper substrate of this panel and the gap between the infrabasal plate produces inequality according to the position of panel, has found the uneven problem of gap value of panel.And, inventor's new discovery the uneven situation in gap of this panel certain tendency is arranged.

Is Figure 29 with this problem representation in the partial top view of the perspective of the problem that is used for illustrating above-mentioned technology.

For panel 10, among sealing strip 7a, the 7b of the seal 7 of formation shaped as frame shape, 7c, the 7d, the zone of the oblique line of representing with E2 among the zone of the oblique line of representing with E1 among the sealing strip 7a and the sealing strip 7d more demonstrates the tendency that gap value reduces than in addition zone.

This be because, sealing strip 7a, the 7d of panel 10 be owing to exist connection electrode formation C of portion and protuberance front end to cut away regional K between sealing strip 7d, the 7a of this panel 10 and adjacent other panels 10, therefore becomes greatly between the sealing strip 7d of the sealing strip 7a of panel 10 and other panels 10 of being adjacent and the interval between the sealing strip 7a of the sealing strip 7d of panel 10 and another panel 10 that is adjacent.

Use the large substrate of Figure 27 to describe, the sealing strip 7a of panel 10-13 and on it sealing strip 7d of adjacent panel 10-3 cut away regional K and come adjacency by connection electrode formation C of portion and protuberance front end are set between them, so these sealing strips 7a separates with the distance of sealing strip 7d.Equally, the sealing strip 7d of panel 10-13 and its sealing strip 7a of adjacent panel 10-23 down cut away regional K and come adjacency by connection electrode formation C of portion and protuberance front end are set between them, so these sealing strips 7d separates with the distance of sealing strip 7a.

On the other hand, the sealing strip 4c of the sealing strip 7b of panel 10-13 and its right neighbour's panel 10-14 is approaching, and the sealing strip 7b of the panel 10-14 that the sealing strip 7c of panel 10-13 and its left side are adjacent is approaching.

Like this, if between large-scale infrabasal plate and large-scale upper substrate, have the zone of the approaching and disposed adjacent of sealing strip and sealing strip separates and the zone of disposed adjacent, then by pressurizeing for large-scale infrabasal plate and large-scale upper substrate are fitted, the thickness deformation of the sealing strip of configuration disconnected from each other is also bigger than the thickness deformation of the sealing strip of configuration near each other.That is, the inventor finds to have occurred big position of the thickness of seal and little position in a panel.

If according to the position of seal and thickness deformation amount difference (promptly, the inequality of the gap value of large-scale infrabasal plate and large-scale upper substrate greatly), then on liquid crystal indicator, use the occasion of this panel, be created in the problem that occurs irregular colour etc. in the demonstration and make color image quality or display quality variation and so on.

Carried out various researchs for the uneven little of the gap value that suppresses large substrate all the time, but the prior art of dealing with the problems referred to above of not finding the inventor and being found.

For example, open in the technology of flat 6-75233 communique record the spy, as shown in figure 30, with the isolation distance of the central portion of large-scale infrabasal plate and large-scale upper substrate, utilize the attraction carried out with pump by unit absorption or wait mechanically and adjust by the pressurization that the unit pressurization is carried out with compressor reducer.And, as represent shown in Figure 30 as vertical view of the configuration pattern of unit, the outside at each frame of the body seal member pattern 301 of the shaped as frame shape of the inlet 304 that is provided with liquid crystal, dispose illusory seal member pattern 303, in the skew that prevents to be applied to the pressing force on the encapsulant in the operation of pushing of substrate.In the sealing part, can not sneak into separaant fully.

In addition, the technology of Te Kaiping 11-14953 communique record, in the outside of the sealing strip of the seal of the formation shaped as frame shape that is formed at shaped as frame shape large substrate,, make the unit interval of the liquid crystal panel behind the large substrate separation cut become even along the sealing strip illusory seal that be arranged in parallel.

Also have, open the technology of putting down in writing in the flat 4-240621 communique the spy, in order in whole scope of a liquid crystal panel, to make thickness at interval even, the quantity of the separaant that long limit disposed of seal that makes the frame shape that is rectangle is with identical in the quantity of the separaant that minor face disposed, interval between two substrates of formation liquid crystal panel is become evenly, make the thickness in the gap of liquid crystal layer become even.

And, used the display panel of liquid crystal general with a pair of transparent relative configuration of substrate that is respectively equipped with transparency electrode and alignment film etc., around the opposite face of these a pair of substrates, dispose the seal that is the shaped as frame shape (seal member) of having sneaked into interval adjustment component (separaant).Inject liquid crystal in this gap between the opposing substrates of surrounding as the electric light converting member with seal.

Below, use Figure 31～Figure 35, describe about the seal of liquid-crystal apparatus.

Liquid crystal panel 101 has infrabasal plate 110 to constitute with the upper substrate 120 of reserving relative configuration at interval therewith.As Figure 32 and shown in Figure 33, the transparency carrier 111 that infrabasal plate 110 will be made of transparent component is as base material, and pattern forms transparency electrode 12 on the face of a side relative with upper substrate 120.Be formed with dielectric film 113 above the transparency electrode 112 at this, prevent the electrical short of the transparency electrode 11 that causes by rubbish etc. and the electrode of upper substrate 120.This infrabasal plate 110 also is formed with alignment film 114 on dielectric film 113.In the occasion that liquid crystal panel 101 uses as the liquid crystal panel of reflection-type, this infrabasal plate 110 also can be transparent or translucent, and, also can be used as the substrate of the panel of the active type that has used TFT, MIM elements such as (TFD).

On the other hand, upper substrate 120 and above-mentioned infrabasal plate 110 are same, on the face of the side relative of the transparency carrier 121 that constitutes by transparent component, dispose with striated or the rectangular color filter 122 that has disposed the pixel of R (red), G (green), B (indigo plant) with infrabasal plate 110.As Figure 32 and shown in Figure 33, configuration planarization film or diaphragm or seal coat 123 are protected color filter 122 below color filter 122, and make the surface of color filter 122 become smooth.Seal coat 123 pattern in its lower section forms transparency electrode 124.In upper substrate 120, formation alignment film 125 below transparency electrode 124 also.

In addition, between the infrabasal plate 110 of liquid crystal panel 101 and upper substrate 120, dispose the seal 130 that is the shaped as frame shape.In sealing part 130, sneaked into separaant 131.By sealing part 130, infrabasal plate 110 and upper substrate 120 are fitted mutually.

This separaant 131 has the certain function of the maintenance of the gap (cell gap) between infrabasal plate 110 and the upper substrate 120.That is, utilize separaant 131, infrabasal plate 110 and upper substrate 120 dispose with predetermined gap.The space that is surrounded by the seal 130 of frame shape becomes the zone of injecting liquid crystal.In this space, inject liquid crystal 140 from inlet shown in Figure 31 132.After the liquid crystal of having filled ormal weight, inlet 132 usefulness sealing resins 133 are sealed.So just form Figure 32 and liquid crystal layer 140 shown in Figure 33.And, in liquid crystal layer 140, be scattered with and be used for the gap between the substrate (cell gap) kept separaant 141 in certain unit.

The liquid crystal panel 101 of Gou Chenging is after the large-scale liquid crystal cells 501 of the liquid crystal panel as large substrate (mother substrate) shown in Figure 34 being got a plurality of usefulness is cut apart cut-out like this, at each liquid crystal cells filling liquid crystal and seal filling orifice and obtain.Cut off the substrate up and down that constitutes this large-scale liquid crystal cells 501 simultaneously along cutting off line X-X1.And, only cut off upper substrate along cutting off line X2-X3, thereby obtain rectangular liquid crystal cells.

From form a line each inlet filling liquid crystal of these liquid crystal cells of the rectangular liquid crystal cells that forms of a plurality of liquid crystal cells, afterwards, after through the operation of sealing regulations such as inlet, cut off the substrate up and down that constitutes liquid crystal cells simultaneously along cut-out line Y-Y1 shown in Figure 34, thereby produce liquid crystal panel one by one.

Large-scale liquid crystal panel 501 as mother substrate shown in Figure 34, the large-scale upper substrate 520 shown in the large-scale infrabasal plate 510 shown in overlapping Figure 35 (A) and Figure 35 (B) forms.Seal 130 mode with the frame of arranging a plurality of rectangles on large-scale infrabasal plate 510 forms.On large-scale upper substrate 520, do not form seal 130 fully.

On the face 510F of the side relative of the large-scale infrabasal plate 510 shown in Figure 35 (A), dispose Figure 32 and transparency electrode 112, dielectric film 113 and alignment film 114 (these are not shown at Figure 35 (A)) shown in Figure 33 with large-scale upper substrate 520.And, on large-scale infrabasal plate 510 with above-mentioned described a plurality of seals 130 that are the shaped as frame shape that dispose.

On the other hand, on the face 520F of the example relative of the large-scale upper substrate 520 shown in Figure 35 (B), dispose Figure 32 and color filter 122, seal coat 123, transparency electrode 124 and alignment film 125 (these are not shown at Figure 35 (B)) shown in Figure 33 with large-scale infrabasal plate 510.

For the liquid crystal panel made from regard to cutting apart 101, there is following problem from this large-scale liquid crystal cells 501.

As shown in figure 31, the extension 110A of infrabasal plate 110 extends from the end face of upper substrate 120.At the limit 130A (disposing the limit of a side of inlet 132) of the limit 130A of the seal of the extension 110A of this infrabasal plate 110 side and the seal relative, sneaked into the separaant 131 of the about 6.0 μ m of particle diameter with the limit 130A of sealing part.Therefore, the thickness of the limit 130A of seal promptly the gap between the opposing substrates of this position by the particle diameter of separaant 131 regulation and on average be about 6 μ m.

And, in the limit 130B of the seal that intersects with the limit 130A of seal, also sneaked into the separaant of identical size and identical material, thus the thickness of the limit 130B of seal promptly the gap between the opposing substrates of this position by the particle diameter regulation of separaant 131 and be on average to be about 6 μ m equally.

But the inventor finds that if the liquid crystal panel of finishing is thrown light on backlight, then the limit 130B at the limit of seal 130A and seal observes different gray scales.So, investigated the result of this reason, the crushing situation of having found the separaant 131 of sneaking into is different with the limit 130B of the seal that extends to the direction at right angle therewith at the limit of seal 130A.Below this content is used Figure 33 of section of the limit 130B of the Figure 32 of section of limit 130A of expression seal and expression seal to describe.

Figure 32 and Figure 33 are illustrated respectively in the crushing situation of the separaant 131 that the limit 130A and the 130B of seal sneaked into.As contrast this Figure 32 and Figure 33 as can be known, and the crushing situation of the separaant 131 of being sneaked at the limit of seal 130A, very bigger than the crushing situation of the separaant 131 of being sneaked at the limit of seal 130B, this is illustrated among Figure 32 turgidly.That is, separaant 131 crushing of Figure 32 are very big, and the gap between the relative substrate at this position is about 5.5 μ m, and on the other hand, the compression of the separaant 131 of Figure 33 is less, and the gap between the relative substrate at this position is about 6.0 μ m.

And, understood that also there are the following problems, because by the about 0.5 μ m of different caused difference gap of the position of

sealing part limit

130A, 130B, at the viewing area of liquid crystal panel shown in Figure 31 101 Z (effective coverage that utilizes as panel) thus around the uneven M of gray scale takes place makes the display quality variation.

So the inventor has investigated because why the difference of the position of this sealing strip produces the seal gray scale inequality on every side of this panel.

The formation of having checked the liquid crystal panel 101 of cutting apart large-scale liquid crystal cells 501 shown in Figure 34 and obtaining its upper substrate and the result in the gap between the infrabasal plate, what understood generation gap S2 (Figure 32) is the corresponding position of limit 130A with the seal shown in Figure 35 (A), and what gap S3 (Figure 33) took place is the corresponding position of limit 130B with the seal shown in Figure 35 (A).

This is owing to following different situations cause, promptly, in large-scale liquid crystal cells 501, the limit 130A of the limit 130A of seal and the seal of adjacency therewith separates than significantly owing to there is extension 110 between, but the limit 130B of seal and the limit 130B of the seal of adjacency is more approaching because between does not have extension 110A therewith.

Promptly, if exert pressure at mutual limit 130B near the seal that disposes (being intensive configuration), then the reacting force of the limit 130B of these seals becomes big, its result, the pressure that is applied to each separaant 131 when making large-scale liquid crystal cells 501 diminishes, its result, there is not the very big situation of crushing in the separaant 131 of sneaking in the sealing part.On the contrary, if the limit 130A at the seal of configuration disconnected from each other exerts pressure, then the reacting force of the limit 130A of these seals diminishes, its result, the pressure that is applied to each separaant 131 when making large-scale liquid crystal cells 501 becomes big, its result, separaant 131 crushing of sneaking in the sealing part are very big.

Infer like this to go up and produce difference at the upper substrate at the position corresponding and the gap S2 between the infrabasal plate (thickness after the distortion of seal) with the upper substrate at the corresponding position of the limit 130B of seal and the gap S3 between the infrabasal plate (thickness after the distortion of seal) with the limit 130A of seal.

Summary of the invention

5. first cut off operation: first of large-scale infrabasal plate 21A that has fitted and large-scale upper substrate 22A cuts off.

At first, by cutting off large-scale infrabasal plate 21A and the large-scale upper substrate 22A that has fitted, make the rectangular panel of a plurality of panel 20 transversely arranged one-tenth one row along cutting off line X3.And then, the one side (protuberance 27 sides) of the rectangular panel that will divide with this cut-out line X3 that cuts off line X3 and next door is cut off along cutting off line X1, thereby cuts away front end and the regional K of the protuberance 27e of inlet.Then, by only cutting off the large-scale upper substrate 22A of this rectangular panel, cut away the unnecessary region D (with reference to Fig. 2) of large-scale upper substrate 22A along cutting off line X2.As if the region D of cutting away this large-scale upper substrate 22A, then on large-scale infrabasal plate 21A, expose the connection electrode 29 of its connection electrode formation C of portion.

In above-mentioned example, at first, form the rectangular panel of dividing with the cut-out line X3 that cuts off line X3 and next door by cutting away large-scale infrabasal plate 21A and large-scale upper substrate 22A simultaneously along cutting off line X3, cut off this rectangular panel along cutting off line X1 then.Replace this, also can form with cutting off line X1 and cutting off the rectangular panel that line X3 divides, cut off this rectangular panel along cutting off line X2 then at first by cutting away large-scale infrabasal plate 21A and large-scale upper substrate 22A along clipping the cut-out line X1 and the X3 that cut off line X2.

Cut away and to use chalker and cutter sweep etc. to carry out.Cut off by these, form inlet 27f toward the outer side and the rectangular panel of the structure of transversely arranged opening (that is, also not injecting the panel of the sky of electric light converting member).

6. the injection of electric light converting member, seal operation: inject the electric light converting member from inlet 27f at the injection zone B that divides with the seal 27 (constituting) that is the shaped as frame shape by sealing

strip

27a, 27b, 27c, 27d.After inject finishing, seal inlet 27f and the electric light converting member is enclosed in the frame of seal 27.In present embodiment 1, use liquid crystal, use the vacuum injection device the disposable injection of liquid crystal as the electric light converting member.Position at inlet 27f after injecting liquid crystal applies the sealing part that is made of the UV hardening resin, this is carried out the ultraviolet ray irradiation and makes the sealing part sclerosis, thereby seal inlet 27f and seal liquid crystal.

As mentioned above, obtain having the rectangular panel of a plurality of panels (having used the occasion of liquid crystal to seal the liquid-crystal apparatus of liquid crystal) of having sealed the electric light converting member as the electric light converting member.

7. second cut off operation: the rectangular panel that a plurality of panels that injected electric light converting members such as liquid crystal are formed a line cuts off the cut-out along cut-out line Y by second, thereby cuts out panel (liquid-crystal apparatus) one by one.

This second cut-out along cut-out line Y of cutting off in the operation is carried out with the method identical with the cut-out in the above-mentioned first cut-out operation.Obtain the panel one by one (liquid-crystal apparatus) finished by along the cut-out of this cut-out line Y.Afterwards, at the top and bottom of single panel configuration Polarizer, on the connection electrode 29 of the connection electrode formation C of portion or splicing ear (COG) such as drive IC of configuration FPC substrate (Flexible Printed Circuit Board) and driving electric light converting member, thereby obtain having multi-purpose liquid-crystal apparatus.

In the present embodiment, as explanation so far, utilize separaant 27n to containing of resinousness adhesives 27m proportional different two kinds of seal member 27-1,27-2 form sealing strips.In detail, with separaant 27n to containing of resinousness adhesives 27m the proportional first high seal member 27-1 be configured in the sealing strip 27a and sealing strip 27d of extension C ' adjacency with connection electrode formation C of portion on.At the sealing strip 27a of a panel (panel 20-14 for example shown in Figure 1) and clip between the sealing strip 27d of another panel (the panel 20-4 of Fig. 1) on its next door that cuts off line X3, exist connection electrode formation C of portion and protuberance front end to cut away regional K, so these sealing strips 27a relatively separate with the interval of sealing strip 27d.

Therefore, these sealing strips 27a and sealing strip 27d accept bigger plus-pressure when pressurization is bonding.To this, on sealing strip 27a and sealing strip 27d, form with first seal of the quantity of the per unit area that comprises more separaant 27n in order to resist from the plus-pressure of outside.

These sealing strips 27a and sealing strip 27d are because the interval between it is also bigger with the interval of sealing strip 27c than sealing strip 27b, therefore do not exist to be configured in the situation that the first seal member 27-1 herein crushes significantly, so can avoid the generation of the big problem of the inequality change of scope internal clearance of the big and panel of the different changes of other sealing strips 27b and the thickness of sealing strip 27c.That is, for sealing strip 27a and sealing strip 27d, by increasing the quantity of antagonism, thereby strengthen the stressed power of antagonism, the problem that can avoid seal 27 compressions that thickness is reduced from the per unit area of the separaant 27n of the in addition power of outside.

On the other hand, the sealing strip 27c of another panel on the sealing strip 27b of a panel and its next door is approaching.These sealing strips 27b and sealing strip 27c form with the second seal member 27-2 to containing of resinousness adhesives proportional low (that is, sneak into the quantity of the separaant in the adhesives of unit quantity few) of separaant 2n.

For example, the sealing strip 27c of the sealing strip 27b of a panel 20-14 and its right neighbour's panel 20-15 is approaching, and is same, and the sealing strip 27b of the panel 20-13 that the sealing strip 27c of this panel 20-14 and a left side are adjacent is approaching.These are near adjacent two sealing strip 27b and sealing strip 27c accept simultaneously to pressurize plus-pressure when bonding, its result, and the plus-pressure of accepting at each sealing strip is disperseed.Therefore, the plus-pressure that applies on each of the sealing strip 27c of the sealing strip 27b of a panel and other adjacent panels diminishes, its result, and the crushing of the seal of sealing strip reduces.Therefore, second seal member that these sealing strips 27b and sealing strip 27c promptly use the quantity of per unit area of the separaant 27n of dispersion also to lack than first seal member forms, also can resist plus-pressure, so the crushing of the seal of sealing strip reduces from the outside.

As mentioned above, as seal, use containing of first high seal member 27-1 of the ratio contain separaant 27n and separaant 27n of the proportional low second seal member 27-2 two kinds.And, if the plus-pressure of pressurization when bonding applies bigger sealing strip with containing of separaant 27n of proportional first high seal member 27-1 formation, on the other hand, plus-pressure apply less sealing strip with containing of separaant 27n the proportional second low seal member 27-2 form, then identical in its crushing of any one sealing strip, can suppress gap uneven less of panel.

In addition, the inequality by the gap reduces, and has injected the liquid-crystal apparatus as the liquid crystal of electric light converting member in panel, can prevent irregular colour, the gray scale inequality of colored display image, can make picture quality become good.And, owing to do not need the configuration of illusory seal of the prior art yet, so thereby even if do not need the configuration space of illusory seal can further make miniaturization, perhaps increase from the peek of the panel of substrate, can reduce cost.Also have, thereby can cut down the effect that seal can also obtain the cost reduction of parts.

The manufacture method of the panel of the foregoing description 2 is described.This manufacture method is substantially the same with the manufacture method (Fig. 4) of the foregoing description 1.Therefore, the explanation of manufacture method herein mainly illustrates the place different with the operation of the foregoing description 1, and the place of same processes only illustrates necessary limit.

Fig. 8 is illustrated in the figure that has formed the situation of the first seal member 47-1 on the large-scale infrabasal plate 41A.

The first seal member 47-1 is formed on sealing strip 47a, the 47d with the extension C ' of infrabasal plate 41A (using as the connection electrode formation C of portion) adjacency.The first seal member 47-1 also be formed at the limit in the outside of large-scale infrabasal plate 41A promptly outside 41A adjacency sealing strip 47A, with the sealing strip 47b of outside 41b adjacency, with the sealing strip 47c of outside 47c adjacency, with the sealing strip 47d of outside 41d adjacency on.

Each sealing strip 47d of panel 40-1,40-2,40-3,40-4 and each sealing strip 47a of panel 40-11,40-12,40-13,40-14 clip above-mentioned extension C ' separate adjacent, so these sealing

strips

47d, 47a form with the first seal member 47-1.

Equally, each sealing strip 47d of panel 40-11,40-12,40-13,40-14 and each sealing strip 47a of panel 40-21,40-22,40-23,40-24 clip above-mentioned extension C ' separate adjacent, so these sealing

strips

47d, 47a also form with the first seal member 47-1.And each sealing strip 47d of panel 40-21,40-22,40-23,40-24 and the extension C ' adjacency that is positioned at its downside are so sealing limit 47d also forms with the first seal member 47-1.

In addition, panel 40-1,40-2,40-3,40-4 each sealing strip 47a and the outside 41a of large-scale infrabasal plate 41A in abutting connection with and aside not near the sealing strip of other panels, so form with the first seal member 47-1.Each sealing strip 47b of panel 40-4,40-14,40-24 and the outside 41b of large-scale infrabasal plate 41A in abutting connection with and do not have the sealing strip of other panels approaching aside, so form with first seal member.Each sealing strip 47c of panel 40-1,40-11,40-21 and the outside 41c of large-scale infrabasal plate 41A in abutting connection with and do not have the sealing strip of other panels approaching aside, so form with the first seal member 47-1.Each sealing strip 47d of panel 40-21,40-23,40-24 and the outside 41d of large-scale infrabasal plate 41A in abutting connection with and do not have the sealing strip of other panels approaching aside, so form with the first seal member 47-1.

As mentioned above, the sealing strip with the outside four limit adjacency of large-scale infrabasal plate 41A also forms with the first seal member 47-1.

Like this, form with the first seal member 47-1 with the sealing strip of extension C ' adjacency with the sealing strip of the outside four limit adjacency of large substrate.

As explanation in the above embodiments 1, there are not sealing strip in sealing

strip

47c, 47a shown in Figure 8,47d on its next door, even perhaps the next door also is positioned at the place that distance is separated.Therefore, the plus-pressure when the pressurization of large-scale infrabasal plate that constitutes large substrate and large-scale upper substrate is bonding is applied to respectively on the seal that forms sealing

strip

47c, 47a, 47d significantly, thereby the thickness deformation of seal is increased.So, the quantity of the separaant 47n of the per unit area by increasing these sealing

strips

47c, 47a, 47d is strengthened the resistibility of relative external force, thereby the thickness deformation of sealing

strip

47c, 47a, 47d is reduced, with the thickness deformation of other sealing strips about equally.Thus, how the place, gap between large-scale infrabasal plate 41A and the large-scale upper substrate 42A all is uniform.

Fig. 9 is illustrated in the figure that has disposed the situation of second seal member 47 on the large-scale upper substrate 42A.

Constitute among 4

sealing strip

47a, 47b, 47c, the 47d of the seal 27 of shaped as frame shape, except be configured in sealing strip 47a, the 47c on the large-scale infrabasal plate 41A, all sealing strips of 47d (with reference to Fig. 8) are configured on the large-scale upper substrate 42A.And, the surface and the back side of large-scale upper substrate 42A shown in Figure 9 is turned over, be superimposed upon on the large-scale infrabasal plate 41A shown in Figure 8.

Specifically, as shown in Figure 9, be configured in the sealing strip 47c of each sealing strip 47b of each sealing strip 47b that sealing strip that the usefulness second seal member 47-2 on the large-scale upper substrate 42A forms is panel 40-1,40-11,40-21, panel 40-2,40-12,40-22,40-3,40-13,40-23 and sealing strip 47c and panel 40-4,40-14,40-24.

The sealing strip that the above-mentioned usefulness second seal member 47-2 forms, as can be known from Fig. 9, sealing strip is approaching each other, and the stressed area of pressurization becomes big when accepting pressurization, the plus-pressure that pressurizes thus when bonding is disperseed, and the plus-pressure that is applied on each sealing strip diminishes.Therefore, even resistibility or stress that the quantity of the per unit area of the separaant 47n of seal member 47-2 also can be fixed for the plus-pressure from the outside less, the thickness deformation of seal is little.

In present embodiment 2, it is screen plate printing method that the manufacture method of each sealing strip is used the manufacture method of the sealing strip in the foregoing description 1.

Like this, make the large-scale infrabasal plate 41A that has formed sealing strip respectively on the whole relative, clip the position between these relative substrates of sealing strip alignment, then, use seal to depress the applying opposing substrates adding with large-scale upper substrate 42A.As shown in Figure 6, obtain the seal 47 of the shaped as frame shape that connected.Pressure method is identical with the manufacture method of the foregoing description 1 with condition with adhering method.

Then, the mother substrate of having fitted is cut off along cut-out line X1, X2, X3, make rectangular panel (blank panel).

In this each panel of the rectangular faceplate that a plurality of panels are formed a line, inject liquid crystal from its gateway, seal inlet with sealing part afterwards, thereby liquid crystal is enclosed in the frame of the seal that is the shaped as frame shape.

Then, the rectangular panel that has injected liquid crystal is cut off along cutting off line Y, obtain each liquid crystal panel or liquid-crystal apparatus shown in Figure 10.

As mentioned above, as seal 47, use and in adhesives 47m, to contain containing of separaant 47n of the proportional high first seal member 47-1 and two kinds of the second seal member 47-2 of this blending ratio low (quantity of sneaking into the separaant in the adhesives of unit quantity is few).

Constitute in 4 sealing strips of the seal be the shaped as frame shape first seal member that contains proportional height (quantity of sneaking into the separaant in the adhesives of unit quantity is many) of the 47n of configuration isolation on applying bigger stressed sealing strip.And, increase the quantity of the separaant 47n of per unit area, and reduce the crushing of the seal of these sealing strips.On the other hand, applying the proportional second low seal member 47-2 that contains of the sub-47n of configuration isolation on the smaller stressed sealing strip.And the quantity of the separaant 47n of minimizing per unit area.Like this, be adjusted to its thickness deformation becomes identical value in which sealing strip that constitutes frame, obtain in full range, having the panel of uniform gap value.This in the liquid-crystal apparatus that the aberration correction is used, reduce error of revising and improve revise precision aspect all effective.

In the foregoing description 2, decide for each sealing strip with relation to form sealing strip, but also the part of the sealing strip part with formation of first seal member and remaining above-mentioned sealing strip can be formed with second seal member with first seal member or with second seal member with the sealing strip on next door.

As mentioned above, in the foregoing description 2, use as seal and to contain containing of separaant 47n of proportional high seal member and contain two kinds of proportional low seal member.Replace it, the ratio that will contain separaant 47n in seal is related with the crushing situation of the seal of sealing strip and be set at three grades or the many grades more than it.If like this, can prevent that the caused gap of stressed difference of each sealing strip from changing, can be adjusted into more uniform gap value.

According to the present invention, be configured in the large-scale infrabasal plate and the seal between the large-scale upper substrate that constitutes large substrate, apply the proportional high seal member that contains of bigger stressed part use separaant 47n, thereby increasing the quantity of the separaant 47n of per unit area.Reduce the crushing of seal thus.On the other hand, do not apply the proportional low seal member that contains that bigger stressed part is used separaant 47n in the seal, thereby reduce the quantity of the separaant 47n of per unit area.Thus, make the thickness deformation of the seal under certain afterburning power become bigger.By like this, can on panel is comprehensive, reduce constituting the upper substrate of a panel and the inequality of the gap value between the infrabasal plate.Its result can improve the precision of round-off error in the liquid-crystal apparatus that the aberration correction is used.

The present invention can also be applied to the seal of rounded shaped as frame shape.Can these be formed with above-mentioned first seal member according to the degree of closeness decision of other seals of a seal of this rounded shaped as frame shape and other rounded shaped as frame shapes still is to form with second seal member.

More than, embodiment 1, embodiment 2 are liquid crystal indicator and the liquid-crystal apparatus that used liquid crystal on the electric light converting member.On the other hand, the substrate with seal member of the present invention can also be applied to touch panel.

Employed touch panels such as the Vehicular navigation system of vehicle mounted, the gap value about using sheet glass or plastic base with 100 μ m from the viewpoint grade of thermotolerance, moisture-proof is made.If gap value is uneven big, then according to the pressing position on the panel, produce position with the stronger power of the action need of finger, only perhaps produce the position that touching a little just produces contact, thereby produce the problem of the misoperation of panel operation.In seal of the present invention,, eliminate aforesaid problem by suppressing the uneven less of gap value.

In addition, seal of the present invention and liquid-crystal apparatus can also be applied to private the occasion of plastic base and glass substrate.And, can also be applied between opposing substrates, seal the EL display device of EL (electroluminescence) etc.

Then, use Figure 11 to Figure 24 that second embodiment of the present invention is described.

First liquid crystal panel 1-1 of Gou Chenging and the following manufacturing of the second liquid crystal panel 1-2 as mentioned above.

To constitute the infrabasal plate of large-scale liquid crystal cells 101-1 and upper substrate so that the relative mode of electrode of establishing is thereon fitted.Through after this baseplate-laminating operation, as shown in figure 21, large-scale liquid crystal cells 101-1 is utilized not shown laser aid or chalker or disconnecting device etc. along cutting off line Y-Y1, cut away the infrabasal plate and the upper substrate that constitute large-scale liquid crystal cells 101-1 simultaneously.Obtain (cutting apart) liquid crystal cells (that is, a plurality of liquid crystal cells form a line connector) of rectangle (oblong-shaped) by this cut-out.

At this rectangular liquid crystal cells, on one side arrange a plurality of inlets 32 at it.This inlet 32 is contacted with the liquid crystal place of accumulating, carry out the disposable injection of vacuum, thereby in rectangular liquid crystal cells, inject liquid crystal and finish the liquid crystal injection process.After injecting liquid crystal, inlet 32 usefulness sealing resins are blocked with the sealing process of sealing the liquid crystal filling orifice.

In order to obtain liquid crystal panel one by one from rectangular liquid crystal panel (becoming liquid crystal panel) by liquid crystal cells, injecting liquid crystal, will be along cutting off rectangular liquid crystal cells that line Y-Y1 direction extends cut-out line X-X1, X2-X3, X4-X5 along perpendicular direction, the directions X that cuts off the upper and lower base plate that constitutes rectangular liquid crystal panel simultaneously cuts off operation.In this cut-out, use the shearing device of laser cutting device, chalker, disconnecting device, cutter sweep etc.

Like this, produce a plurality of first, second liquid crystal panel 1-1,1-2 from large-scale liquid crystal cells 101-1.

Large-scale liquid crystal cells 101-1 shown in Figure 21 is cut apart by cut-out, thereby obtain a plurality of liquid crystal cells (in liquid crystal cells, inject liquid crystal and then become the first liquid crystal panel 1-1 or the second liquid crystal panel 1-2), at this moment, in the periphery of large-scale liquid crystal cells 101-1, produce the part do not become liquid crystal panel and residual baseplate part 66-1, the 66-2 of giving up.Giving up between the position of baseplate part the 66-1 corresponding upper substrate and infrabasal plate, be configured in the illusory seal 35 of explanation among the embodiment 3 with this.

The large-scale liquid crystal cells 101-1 of Figure 21 is made of the upper substrate shown in the infrabasal plate shown in Figure 24 (A) (below, this is called large-scale infrabasal plate 501-2) and Figure 24 (B) (below, this is called large-scale upper substrate 201-2).

On the face 101-2F of the side relative with large-scale upper substrate 201-2 of the large-scale infrabasal plate 501-2 shown in 24 (A), it is the second seal member 30B of the second separaant 31B of about 6.0 μ m that mean grain size d has been sneaked in configuration.And, on the illusory seal 35 that is disposed on this face 101-2F, also use and the identical parts of the second seal member 30B.

On the other hand, on the face 201-2F of the side relative with large-scale infrabasal plate 101-2 of the large-scale upper substrate 201-2 shown in 24 (B), it is the first seal member 30A of the first separaant 31A of about 6.5 μ m that mean grain size d has been sneaked in configuration.And, on the illusory seal 35 that is disposed on this face 201-2F, also use and the identical parts of the first seal member 30A.

Like this, on large-scale infrabasal plate 101-2 and large-scale upper substrate 201-2, make in the seal particle diameter of separaant different.In present embodiment 4, it is little to make the particle diameter ratio of separaant in the seal that is configured on the large-scale upper substrate be configured in the particle diameter of separaant in the seal on the large-scale infrabasal plate.

The liquid crystal panel 1-1 of the present embodiment 4 of Gou Chenging and liquid crystal panel 1-2 as mentioned above, except effect with the foregoing description 3, because the extension 20A of liquid crystal panel 1-1 and the extension 50A of liquid crystal panel 1-2 are forming differently mutually up and down, so have the large substrate that increases liquid crystal panel or from the effect of the peek of the liquid crystal panel of large substrate.This is because can not compare obvious minimizing with embodiment 1 as the baseplate part of giving up that panel uses.Therefore, have production cost reduction, obtain the effect of the low price of panel.

And, solved the problem of gray scale inequality, also have the effect that the quality of display quality or panel improves.

In the foregoing description 4 since with seal with the configuration of the manufacture method of print process, so on each of upper substrate and infrabasal plate separate configuration seal member 30A and seal member 30B.But, in the present embodiment, if with seal with the configuration of the manufacture method of apportion design, even divided seal on upper substrate and infrabasal plate not then, also only configuration seal member 30A and seal member 30B on a substrate.For example, if only on a substrate, dispose seal member 30A and seal member 30B, then with the pattern arrangement shown in Figure 35 (A) and Figure 35 (B).At this moment, in order separately to use the particle diameter of separaant according to the position of the regulation of seal, scatter cover and in separaant scatters, be provided with.Utilize this position that covers on regulation to scatter the separaant of regulation.

In the foregoing description 4, as liquid crystal cells, used alignment film, but when the present invention being used for PN (polymer network) liquid crystal, do not had alignment film also passable.

As finishing liquid crystal panel, in liquid crystal panel, append and use Polarizer etc., but, then do not have Polarizer also passable if finish the PN liquid crystal panel.

More than, in second embodiment, the example that has used liquid crystal as the electric light converting member has been described, but in addition, also can have used EL (electroluminescence) as the electric light converting member, in this occasion, can expect and the identical effect of occasion of using liquid crystal.

And second embodiment can also be applied to following liquid crystal panel or liquid-crystal apparatus.

Substrate can also be applied to plastic base except glass substrate.Liquid-crystal apparatus is not limited to transmission-type, also can be in addition reflection-type or Semitransmissive.And, except the matrix liquid crystal device of passive mode, also can be to use the liquid-crystal apparatus of the active type of elements such as TFT, MIN.Except the liquid-crystal apparatus of matrix form, also can be the liquid-crystal apparatus of static form.

In addition, in the present embodiment, the particle diameter that is the separaant on the limit of seal of shaped as frame shape is identical in its all scope, but also can change the particle diameter that be included in separaant wherein in a part on one side and rest parts.

Below, use Figure 25 A, Figure 25 B and Figure 26 that the 3rd embodiment of the present invention is described.

In above-mentioned first embodiment and second embodiment, control the amount in the gap of large-scale infrabasal plate and large-scale upper substrate with spherical separaant.

In the 3rd embodiment, as the gap adjustment component will the cross section shown in Figure 25 A or Figure 25 B be rectangle, quadrilateral, gap adjustment component trapezoidal, leg-of-mutton column be that separaant is configured in the position that disposes seal at least, disposed the insulativity adhesives in the mode as the gap adjustment component that covers column as seal member.

The gap adjustment component of column is not necessarily to be confined to column, so hereinafter referred to as fixing separaant.On the other hand, from the viewpoint of making, preferably the gap adjustment component of column.

That is,, at first form the separaant of the column of fixed type at the position of configuration seal.Then, be configured in above-mentioned seal configuration position with the insulativity adhering resin that will have the seal function as the mode that covers the fixedly separaant that forms like this.Thus, can form the inner fixedly seal of separaant that exists.Fixedly separaant also is configured in the position of configuration seal in addition with passable.

Embodiment 5

In this embodiment 5, utilize the height of the separaant 57 of the column shown in Figure 25 A or Figure 25 B, adjust the amount in the gap (with reference to Fig. 2) of large-scale infrabasal plate 21A and large-scale upper substrate 22A.

In addition, the quantity of fixedly separaant that can be used in the position of configuration seal will dispose the density of the fixedly separaant on the position of the seal what wait, and carries out above-mentioned adjustment.As above-mentioned density, number by the fixing sectional area of separaant of will multiplying each other on the quantity of the fixedly separaant that is disposed on the single face area at position of configuration seal is divided by the above-mentioned unit area of seal, thereby can access the contrast benchmark of the density of the fixedly separaant on the position of seal.

The contrast benchmark of the density of the fixedly separaant on the position of seal, the sectional area of the fixedly separaant that unit area disposed at the position of height of the fixedly separaant that is disposed on the unit area at the quantity of the fixedly separaant that is disposed on can the unit area at position with the configuration seal or the position of configuration seal (changing this highly is exactly the height that changes the fixedly separaant before bonding) or configuration seal (changes this sectional area, change the fixedly separaant before bonding sectional area situation and set the situation of the condition of the fixedly separaant before bonding in the mode of the sectional area that changes the fixedly separaant after bonding) benchmark as a comparison, also can be with these each contrast benchmark combination.

By like this with fixing configuration fixedly separaant dispose million positions that dispose seal at least, thereby eliminate the upper substrate that constitutes panel and the inequality in the gap between the following base cloth, obtained not occurring effect according to the inequality of the thickness at the position of panel.

The figure that a panel 20-14 in the large substrate of Fig. 1 has been had an X-rayed in use is that Fig. 3 illustrates this embodiment 5.

With the sealing strip 27d of the extension C ' as the connection electrode formation C of portion (on the large-scale infrabasal plate 21A) adjacency of this panel 20-14 and with the sealing strip 27a of the extension C ' adjacency of the panel 20-4 that is adjacent to panel 20-14, with the first seal member 27-1 formation of the density height (quantity of the fixedly separaant that is disposed on the unit area of the area of configuration seal is many) of the fixedly separaant 47 of configuration.

On the other hand, sealing strip 27b forms with the second seal member 27-2 of the density low (quantity few (the relative first seal member 27-1, the second seal member 27-2 is few in the quantity of the fixedly separaant that unit area disposed) of the fixedly separaant that is disposed on the unit area of the area of configuration seal) of the fixedly separaant 57 of configuration with sealing strip 27c.

By the fixing separaant of such configuration since with the described identical reason of first embodiment, can prevent according to the upper substrate at panel position and the inequality in the interval between the infrabasal plate (gap).Promptly, because relatively separate at the interval of the sealing strip 27d of sealing strip 27a and other panels adjacent with sealing strip 27a, the plus-pressure that hiding above-mentioned sealing strip 27a and above-mentioned sealing strip 27d apply when bonding upper substrate of pressurization and infrabasal plate is bigger, and for this pressurization, configuration density by will having improved fixing separaant as mentioned above and/or improved the height of fixing separaant and/or strengthened fixedly that above-mentioned first seal member of the sectional area of separaant is used for sealing strip 27a and sealing strip 27d, thus bigger resistance can be provided for bigger pressure from the outside.

Its result, the effect of the following problem that can be resolved, be that sealing strip 27a and sealing strip 27d reduce the gap than sealing strip in addition (sealing strip 27b and sealing strip 27c) the earth crushing that constitutes a panel, thereby big with the different changes of the gap value of these sealing strips 27b and sealing strip 27c, become big problem in the inequality of the scope internal clearance of a panel.

And, the liquid crystal panel of this embodiment 5 of the present invention, cut the sealing the liquid crystal panel of structure of liquid crystal while having at least of at least one substrate of the bonding opposing substrates of seal with gap adjustment component forming from the extension that extends of another substrate and in the inboard of sealing part by being the shaped as frame shape, be have configuration density than with the limit of the above-mentioned seal of the limit adjacency of the aforesaid substrate that forms above-mentioned extension on the above-mentioned liquid crystal panel of low other the above-mentioned sealing strips of the configuration density of the fixedly separaant that disposed, as the basic structure that is used to obtain above-mentioned feature, can be organized into following content as an individual system.
